🎙️Genetic Genealogy and DNA: Interview with Pablo Blanco on the University of Seville Podcast

🎧 In the recent episode of the University of Seville's podcast, "The Tree of Your History," genealogy specialist Pablo Blanco, partner at ADN y Genealogía (DNA and Genealogy), offers a clear and practical perspective on how genetic genealogy and DNA analysis can help delve deeper into family history research.

🧬 What is genetic genealogy and why does it matter?

Genetic genealogy is a discipline that combines traditional genealogical research with DNA testing, allowing researchers to infer biological connections and ancestral origins that, in many cases, are not visible through historical documents alone.

Thanks to advances in genome sequencing and the availability of tests accessible to the general public, it is now possible to:

• Validate or expand family trees with genetic evidence.

• Discover potential family relationships even when official records are missing.

• Explore the ancestral makeup of each individual in terms of genetic groups.

🎧 Highlights from the interview with Pablo Blanco

During the interview, Pablo Blanco shared his perspective on how genetics does not replace documentary genealogy, but rather integrates as a powerful complementary tool. Some of the most interesting points were:

🔍 1. Integrating DNA into family research

Pablo explained that genetic tests can help confirm or challenge hypotheses about the family tree. When the results show an ethnic origin or genetic lineage that doesn't match documented data, this offers clues for new lines of research that would previously have been impossible to pursue.

🧬 2. Types of DNA Tests and Their Uses

Not all DNA tests serve the same purpose. In the interview, it was explained—as is common in the field—that:

• Autosomal tests: show the overall genetic makeup and can detect familial matches up to approximately the 5th degree.

• Y-DNA and mitochondrial DNA (mtDNA): allow for tracing male and female lineages across many generations.

This distinction is key for those seeking specific ancestors or validation of particular family branches, such as families tracing their roots in distant countries or paternal/maternal lines that disappear from historical records.

🧠 3. Genealogy and the Scientific Revolution

Pablo also emphasized that genetic genealogy represents a revolution for researchers, while acknowledging that its integration with classical methods still requires expert judgment and is not an instant solution on its own.

🧠 Why this episode is relevant for those researching their family history

This episode is not only interesting for history buffs, but especially for those who are starting or expanding their genealogical research. Understanding:

• How to apply DNA results to your family tree,

• What types of tests exist,

• What each one contributes, is invaluable, both for validating data and for discovering new family ties that documents don't reveal.
